Since March 22, "SONG 1" has transformed the exterior of the cylindrical museum into something of an outdoor cinema, casting nightly 360-degree projections onto the 82-foot building. The project's soundtrack has featured spliced-together renditions of the crooner staple "I Only Have Eyes for You" by Beck, Oneohtrix Point Never, No Age, Devendra Banhart, Lucky Dragons, and more.

At tonight's "Happening", the pre-recorded "SONG 1" soundtrack will be replaced by a live, continuous soundscape. Across multiple stages, artists will perform in accordance with a script organized by Aitken. Their various interpretations of "I Only Have Eyes for You" will blend seemlessly with help from Animal Collective's Geologist, who will DJ various versions of the song in between bands. Nicolas Jaar will sample and loop the set preceeding his own; No Age will perform with gospel singers. The program will run 75 minutes. Pitchfork editor Brandon Stosuy is tweeting from the event.
